Radio Access Network (RAN) virtualization, aptly known as Cloud-RAN is fast becoming the technology buzz-word in the telecom sector following the growth in Network Function Virtualization (NFV) adoption across network segments especially the core network and data center elements. This newest technology frontier in the RAN technology requires compatible and well matched fronthaul networks which include small cells, to enable broader applicability in today's heterogeneous networks (HetNets).
The Small Cell Forum (www.smallcellforum.org) has recently included virtualization work stream as part of its Release Program to evaluate various option for optimal virtualization deployment in the small cells network.
Launched in February 2013 the Small Cell Forum Release Program provides a comprehensive set of technical and business documents to help deploy small cells in the home, enterprise, rural and urban areas. Each release includes detailed documents on key areas such as market drivers, business case, and technology information including standards, operator lessons and a regulatory overview.
“Cloud-RAN and small cells have often been presented as alternatives. We believe that virtualization techniques can be re-applied to small cell architectures. This work will help ensure that in dense HetNets, small cells are fully interworking with other platforms to create the broadest pool of capacity and most efficient use of shared resources.”
- Gordon Mansfield, Chair of Small Cell Forum
“Operators need to understand how small cells fit into the Cloud-RAN story. We believe there will be better ROI if operators can plan virtualization across the entire HetNet, including small cells, rather than as a separate exercise. This work stream will consider the impact of such an approach on everything from network architecture to the business case. We are now inviting Forum members and the wider industry to get behind this initiative and help shape the future of mobile networks through our Release work.”
